left and right headphone test
A headset with swapped sides, a speaker wired backwards or bass that vanishes are easy problems to find with test signals. This page opens the stereo audio test ready to go: tap Left, Right, Both or Phase and check the result with your ears.
Check that the headset is on the right way round, the system balance and any channel swap in equalizer apps.
Normal for small headphones and laptop speakers. Deep bass needs a subwoofer or headphones with a larger driver.
Tap Left: sound should come only from the left side, and the same goes for Right. If the sides are swapped, check the cable, the system balance and the app's equalizer.
The starting volume is low and the control has a moderate maximum, but loud low and high tones can strain any speaker. Start with the system volume low and raise it slowly.
Yes. Bluetooth headphones play the test normally, but codec compression and bandwidth limits can cut treble above roughly 16 to 20 kHz.
Noise spreads energy over all frequencies and sounds louder than a tone of the same amplitude. That is why pink noise enters at half the level of the tone.
